Hydrogen peroxide formulations in barrier layer films with a metallized layer

ABSTRACT

The present invention concerns a cosmetic product for modifying the natural color of keratinous fibers, in particular human hair, which contains at least one packaging (VP) and a cosmetic composition (KM) contained in this packaging (VP). The packaging is made of a multi-layer film (F) comprising at least two polymer layers (P1) and (P2) and at least one barrier layer (BS). The cosmetic composition comprises at least one oxidizing agent, at least one C8-C30 alcohol and at least one non-ionic surfactant. The use of the packaging (VP) in combination with the cosmetic composition (KM) surprisingly does not lead to an inflation of the packaging or an excessive water loss of the agent (KM) during storage.

TECHNICAL FIELD

The present disclosure is in the field of cosmetics and concerns aproduct for the oxidative color change of keratinous fibers, inparticular human hair, comprising a composition containing an oxidizingagent packed in a package. The oxidant-containing composition containsat least one C₈-C₃₀ alcohol and at least one non-ionic surfactant. Thepackaging is a package manufactured from a special multi-layer filmcomposite system, the wall of which comprises at least two polymericlayers and a barrier layer. The barrier layer has a penetration barriereffect for gases and water vapor. The barrier layer comprises a metal.

BACKGROUND

Changing the color of keratinous fibers, especially of hair, is animportant area of modern cosmetics. The appearance of the hair may beadjusted to current fashion trends as well as to the individual wishesof each person. The expert knows various ways to change the color ofhair. The hair colour may be temporarily changed by the use of directdyes. In this process, already formed dyes diffuse from the dye into thehair fiber. Dyeing with direct dyes is associated with a low level ofhair damage, but a disadvantage is the low durability and the fastwashability of the colorations obtained with direct dyes.

If the consumer wants a long-lasting color result or a shade that islighter than the original hair color, oxidative color changing agentsare usually used. For permanent, intensive colorations withcorresponding fastness properties, so-called oxidative colorants areused. Such dyes usually contain oxidation dye precursors, so-calleddeveloper and coupler components, which form the actual dyes under theinfluence of oxidizing agents—usually hydrogen peroxide. Oxidativecolorants are exemplified by excellent, long-lasting dyeing results.

Oxidative color modifiers are usually marketed in the form oftwo-component agents, in which two different compositions are separatelypackaged in two separate packages and are not mixed together untilshortly before use. The first composition is a formulation—usuallyacidic for stability reasons—which contains, for example, hydrogenperoxide as an oxidizing agent in concentrations of from about 1.5 toabout 12% by weight. The oxidizing agent formulation is usually in theform of an emulsion or dispersion and is usually provided in a plasticbottle with a reclosable outlet opening (developer bottle).

This oxidizing agent formulation is mixed with a second compositionbefore use. This second composition is an alkaline formulation which isoften in the form of a cream or a gel and which, if a color change isdesired simultaneously with the brightening, additionally contains atleast one oxidation dye precursor. This second formulation may beprovided, for example, in the form of a tube or in the form of a plasticor glass container.

In the usual embodiment described above, the second composition, whichcontains the alkalizing agent and/or the oxidation dye precursors, istransferred from the tube or container into the developer bottle andthen mixed by shaking with the hydrogen peroxide composition already inthe developer bottle. In this way, the application mixture is preparedin the developer bottle. Application to the hair is then effected via asmall spout or outlet on the head of the developer bottle. The spout oroutlet opening is opened after shaking, and the application mixture canbe removed by pressing the flexible developer bottle.

The use of the developer bottle requires a certain routine from theuser, so that some users prefer to prepare the application mixture in amixing bowl and apply it with a brush.

When preparing the application mixture in a mixing bowl, bothcomponents—the first composition containing the oxidizing agent and thesecond composition containing an alkalizing agent and/or oxidation dyeprecursor—are completely transferred into a bowl or similar vessel andstirred there, for example with the aid of a brush. The applicationmixture is then removed from the mixing bowl with a brush. With thisform of application, the use of a voluminous and expensive developerbottle is not necessary, and the search continues for inexpensive andmaterial-saving packaging forms for the oxidizing agent composition.

As an inexpensive form of packaging with low material consumption,packaging in the form of bags or pouches, which are usually made ofplastic films or metal foils, is suitable in this respect.

This type of packaging may, for example, be produced by gluing or hotpressing two plastic films on top of each other, with the gluing takingplace on all edges of the films. The interior of the packaging (i.e. theplastic bag) created by bonding may then be filled with the desiredcosmetic composition. The packaging may be opened by tearing or cuttingthe plastic bag open.

However, filling oxidizing agent compositions into such packaging isassociated with problems caused by the reactivity of the oxidizingagent. Oxidizing agents are highly reactive substances which—dependingon the storage conditions and, where applicable, on the presence ofdecomposing impurities—decompose in small fractions to form oxygen (i.e.gas).

Developer bottles known from the state of the art are usually onlyfilled with the oxidizing agent composition to a maximum of half,usually only to a third of their internal volume. As a rule, developerbottles are made of polyethylene. Since polyethylene is permeable toboth water vapor and other gases, there is no or only very slight excesspressure in the developer bottle. In addition, developer bottles areusually provided with stable, thick walls and a sturdy screw cap, sothat the diffusion of water vapor or gases through the thickness of thewalls is reduced and a slight increase in pressure within the bottle hasno negative effects.

In contrast, bag-shaped packaging is usually completely filled with theliquid composition, and there is practically no excess air space in thefilled bag. In addition, such packaging should be flexible, and whenopened (e.g. torn open or cut open) there should be no uncontrolledescape of the composition. For this reason, when packaging liquidcompositions, the creation of excess pressure in the packaging should,if possible, be avoided.

If an oxidizing agent composition is in such a package, the gas (oxygen)produced during storage may cause the package to expand. Since the edgesof the packaging are usually only glued together, in the worst case,strong inflation can lead to bursting of the packaging. For thesereasons, the choice of film material used for the packaging is of greatimportance when storing oxidizing agent-containing compositions.

Packaging made of pure plastic such as polyethylene or polypropylene ispermeable to both water vapor and gases. When storing oxidizingagent-containing compositions in polyethylene or polypropylenepackaging, the packaging does not expand. Due to the high permeabilityof the comparatively thin film of the packaging to water vapor, however,the water content of the composition is reduced. If the composition isstored in the packaging for several weeks or months, the water lossexceeds the maximum value permitted for adequate storage stability.

The production of suitable packaging for hydrogen peroxide-containingformulations is a challenge. The above mentioned properties for thepermeability of oxygen and water vapor must be adjusted to ensuresufficient storage stability. The thickness of the film layer should bekept as low as possible for environmental reasons and to conserveresources. Furthermore, the layer thickness naturally also has aninfluence on the manufacturing costs. Against this background, thinlayers are desired, but these do not always guarantee sufficientmechanical strength. If different materials are combined in amulti-layer film to meet a wide range of requirements, themanufacturability of the multi-layer film must also be guaranteed.Certain materials cannot be combined with each other because thecohesion between layers is not always sufficient or because theirprocessing temperatures may be so different that joint processing isdifficult.

Finally, the film materials are of great importance, especially whenstoring a multi-component system, as substances from the multi-componentsystem can diffuse into the films and promote the detachment of layersforming the film. The choice of components in a hydrogenperoxide-containing formulation therefore also has an influence on thechoice of packaging.

BRIEF SUMMARY

A cosmetic product is provided for modifying the natural color ofkeratinous fibers, in particular human hair. The cosmetic productcontains at least one packaging and a cosmetic composition contained inthe packaging. The packaging is made of a multi-layer film comprising atleast two polymer layers and and at least one barrier layer. The firstpolymer layer is formed of polyethylene terephthalate or polyethylenenaphthalate, and the second polymer layer is formed of a polyolefin. Thecosmetic composition comprises at least one oxidizing compound, at leastone C₈-C₃₀ alcohol and at least one non-ionic surfactant.

One purpose of the present disclosure is to package formulationscontaining hydrogen peroxide in such a way that the mechanical strengthof the packaging is sufficiently high to allow safe storage, whileensuring easy access to the ingredients.

DETAILED DESCRIPTION

The following detailed description is merely exemplary in nature and isnot intended to limit the disclosure or the application and uses of thesubject matter as described herein. Furthermore, there is no intentionto be bound by any theory presented in the preceding background or thefollowing detailed description.

Surprisingly, it has now been found that oxidizing agent-containingcompositions may be packaged where the water vapor permeability is lowand bloating may be reduced by allowing the film to have a certain levelof oxygen permeability. The films include a special film compositesystem and additionally have a barrier layer. By reducing the watervapor permeability, but adjusting the oxygen permeability to asufficiently high level, the tendency to expand due to oxygen formedfrom the hydrogen peroxide is reduced and the mechanical strength isincreased over time.

The subject-matter of the present disclosure is a cosmetic product foraltering the natural color of keratinous fibers, in particular humanhair, comprising

-   (i) at least one packaging (VP) comprising at least one multi-layer    film (F) comprising at least one first polymer layer (P1), at least    one second polymer layer (P2) and at least one barrier layer (BS),    and-   (ii) at least one cosmetic composition (KM) packaged in the    packaging (VP)and containing:-   a) at least one oxidizing compound,-   b) at least one C₈-C₃₀ alcohol, and-   c) at least one non-ionic surfactant,-   wherein the first polymer layer (P1) is formed of polyethylene    terephthalate or polyethylene naphthalate, in particular    polyethylene terephthalate, the second polymer layer (P2) is formed    of a polyolefin, in particular polyethylene and the barrier layer    (BS) is formed of metallized oriented polypropylene.

Keratinous fibers, keratin-containing fibers or keratin fibers areunderstood to be furs, wool, feathers and in particular human hair.Although the agents as contemplated herein are primarily suitable forlightening and dyeing keratin fibers, there is nothing in principle toprevent their use in other areas.

The product as contemplated herein is a product for the oxidative colorchange of keratinous fibers, i.e. a product which is applied to thehuman head to achieve an oxidative coloring, a lightening, a bleachingor a color shade change of the hair. In this context, color shade meansa coloring in which the color result is lighter than the original haircolor. That the product is to be used “to change the natural color”means that the product either comprises only an oxidizing agent forbleaching[A1], or that the product comprises an oxidizing agent usedwith a coupler not belonging to the present disclosure to achieve acolor change, or that the product is used with a dye not belonging tothe present disclosure for further tinting.

Furthermore, the term “packaging” is understood to mean, as contemplatedherein, a packaging which is preferably in the form of a sachet. Asachet is a small packaging in pocket or bag form, which is often usedfor the packaging of cosmetics. The capacity of the packaging, inparticular of the sachet, may be from about 5 to about 1000 ml,preferably from about 10 to about 200 ml and particularly preferablyfrom about 20 to about 50 ml.

In addition, a multi-layer film (F) in the context of the presentdisclosure is understood to be a thin, flat and reelable sheet includingthe at least one polymer layer (P1) and the at least one polymer layer(P2). This multi-layer film (F) forms the wall of the packaging (VP).The packaging also contains a barrier layer (BS), which selectivelyallows or reduces the passage of water vapor and other gases such asoxygen.

The cosmetic product as contemplated herein comprises as first componenta packaging (VP) which comprises at least one multi-layer film (F). Thisfilm comprises at least one first polymer layer (P1), at least onesecond polymer layer (P2) and at least one barrier layer (BS). Thismulti-layer film forms the wall or the outer shell of the packaging. Asdescribed above, this type of packaging is usually produced by gluing,pressing or welding two pieces of film on top of each other (thepackaging (VP) is filled simultaneously with the cosmetic composition(KM)), i.e. such packaging is closed at all edges. This packaging may beopened, for example, by tearing or cutting open.

The thickness of the multi-layer film (F) determines the mechanicalproperties and strength of the films. It should be designed in such away that there is sufficient mechanical stability, but at the same timethe film (F)—and thus the packaging (VP) made from the film—should beflexible enough to allow complete removal of the cosmetic compositions(KM) from the opened packaging (VP) by pressing or squeezing. A filmmeets these requirements if the film (F) has a certain total thickness.Preferred embodiments of the present disclosure that the at least onemulti-layer film has a total thickness of from about 28 μm to about 220μm, preferably of from about 52 μm to about 180 μm, more preferably offrom about 80 μm to about 140 μm. For the purposes of the presentdisclosure, the total thickness of the film (F) is understood to be thesum of the thicknesses of all individual layers of which the film (F)consists.

The configuration of the layers (P1), (P2) and (BS) within themulti-layer film (F) may vary. Furthermore, it is also possible that thefilm (F) comprises further layers in addition to the previouslymentioned layers, and as contemplated herein it is advantageous if allpreviously mentioned layers are oriented parallel to the surfaces of thefilm (F), i.e. all layers have the same orientation. If the multi-layerfilm (F) contains the three layers (P1), (P2) and (BS) described above,the following configurations of the layers would be possible (viewedfrom the interior (in contact with the cosmetic composition (KM)) to theexterior)

-   a) *Interior*—Layer (P1)—Layer (P2)—Barrier layer (BS)—*Exterior*,-   b) *Interior*—Layer (P1)—Barrier layer (BS)—Layer (P2)—*Exterior*,-   c) *Interior*—Layer (P2)—Layer (P1) —Barrier layer (BS)—*Exterior*,-   d) *Interior*—Layer (P2)—Barrier layer (BS)—Layer (P1)—*Exterior*,-   e) *Interior*—Barrier layer (BS)—Layer (P1)—Layer (P2)—*Exterior*,-   f) *Interior*—Barrier layer (BS)—Layer (P2)—Layer (P1)—*Exterior*.

However, as contemplated herein, it is preferred if the barrier layer(BS) is located between the first polymer layer (P1) and the secondpolymer layer (P2), the second polymer layer (P2) being located on theoutside of the packaging. In this case, the multi-layer film (F)includes three layers, the layer (P1) being at the innermost and incontact with the cosmetic composition (KM). Layer (P1) is in contactwith the barrier layer (BS) and the barrier layer (BS) is in contactwith layer (P2). In this layout, the layers (P1) and (P2) are notadjacent to each other, but are separated by the barrier layer (BS). Thespecial advantage of this arrangement is that the—often verythin—barrier layer (BS) is not located on either the inner or outersurface of the multi-layer film (F), but is protected by the polymerlayer (P1) in the direction of the inside and by the polymer layer (P2)in the direction of the outside. In this way, mechanical abrasion ormechanical destruction of the barrier layer (BS) can be avoided as faras possible. It is therefore advantageous in the context of the presentdisclosure if the at least one multi-layer film (F) contains the atleast one barrier layer (BS) between the at least one first polymerlayer (P1) and the at least one second polymer layer (P2). The use ofsuch packaging has been shown to be particularly advantageous in termsof increased storage stability, as this arrangement does not exhibitpuffing or delamination on prolonged contact with an oxidizingagent-containing composition. In a further preferred embodiment, thebarrier layer (BS) is also located between the two polymer layers P1 andP2, but with the first polymer layer (P1) on the outside of thepackaging.

As contemplated herein, the outside of the packaging (VP) is that sideof the packaging which does not come into contact with the cosmeticcomposition (KM) but with the environment. The use of such packaging hasproven to be particularly advantageous in terms of increased storagestability, as this configuration shows neither swelling nor delaminationduring prolonged contact time with a composition containing oxidizingagents.

As contemplated herein, the first polymeric material of the first layer(P1) is a polyester. This material may be a layer of one type of polymeror a layer of a polymer mixture. According to the present disclosure,the at least one first polymer layer (P1) is formed from polyethyleneterephthalate or polyethylene naphthalate, in particular frompolyethylene terephthalate. As contemplated herein, the term “formed” isunderstood to mean that the polymer layer contains at least about 70% byweight, preferably at least about 80% by weight, more preferably atleast about 90% by weight, in particular at least about 99% by weight,in each case based on the total weight of the polymer layer (P1), of theaforementioned compounds.

Polyethylene terephthalate (PET) is a polymer from the group ofpolyesters. Polyethylene terephthalate may, for example, be produced bytransesterification of dimethyl terephthalate with ethylene glycol atelevated temperatures. In this transesterification reaction, methanol issplit off, which is removed by distillation. The resultingbis(2-hydroxyethyl)-terephthalate is converted to PET bypolycondensation, again producing ethylene glycol. Another method ofproducing polyethylene terephthalate is the direct polycondensation ofethylene glycol and terephthalic acid at high temperatures withdistillation of the resulting water. Polyethylene terephthalate isexemplified by a particularly high mechanical strength. If the PET layerforms the outer layer, this also offers the advantage that the layerunderneath may be printed without the print being rubbed off. The PETlayer is transparent and provides a mechanical protective layer for theprinting layer.

According to a preferred embodiment of the present disclosure, the layerthickness of the first polymer layer (P1) is from about 4 μm to about 50μm, preferably from about 5 μm to about 35 μm, more preferably fromabout 6 μm to about 20 μm. The layer thickness of the PET layer usedaccording to the preferred embodiment of the present disclosure isassociated with special advantages, which are related to generalproperties of PET. PET is exemplified by a high dimensionalstability/stiffness. If PET with these thicknesses is chosen as thefirst polymer layer (P1), this offers the film an advantageousmechanical dimensional stability. At the same time, the overallthickness of the film may be kept low, so that a material andresource-saving film may be provided.

Furthermore, the multi-layer film (F) from which the packaging isproduced comprises a second polymer layer (P2) made of a secondpolymeric material. The second polymeric material may be a layer of onepolymer type or a layer of a polymer mixture. It is intended in thecontext of the present disclosure that the at least one second polymerlayer (P2) is formed of a polyolefin, in particular of polyethylene. Ascontemplated herein, the term “formed” is understood to mean that thepolymer layer contains at least about 70% by weight, preferably at leastabout 80% by weight, more preferably at least about 90% by weight, inparticular at least about 99% by weight, in each case based on the totalweight of the polymer layer (P2), of the above-mentioned compounds.

The second polymeric material of the second layer (P2) of themulti-layer film (F) is a polyolefin, in particular polyethylene.Polyolefins are polymers which are produced from alkenes such asethylene, propylene, 1-butene or isobutene by chain polymerization. Theyare semi-crystalline thermoplasts which are easy to process. They areexemplified by good chemical resistance. Polyethylene and polypropyleneare widely used in film applications. As contemplated herein,polypropylene is therefore used for the second layer (P2), butpolyethylene is preferred. Polyethylene is produced by polymerization ofethylene using various catalysts. Polyethylene may, for example, beproduced by polymerizing ethylene in the gas phase or in suspension. Theaverage relative molar mass may, for example, be controlled by setting acertain hydrogen partial pressure during the polymerization of ethylene.The processing of polyethylene may be done for example by extrusion andstretch blow molding, or by pressing, calendering, thermoforming andcold forming.

The second polymer layer (P2) serves as a support layer. Althoughpolyethylene has the disadvantage of being permeable to oxygen and watervapor, it has the advantage of being inexpensive and, due to its lowmelting point—lower than that of polypropylene—it may be processedeasily and in an energy-saving manner.

According to a preferred embodiment of the present disclosure, thesecond polymer layer (P2) has a certain layer thickness. According to apreferred embodiment of the present disclosure, the second polymer layer(P2) has a layer thickness of from about 20 μm to about 150 μm,preferably of from about 30 μm to about 110 μm, more preferably of fromabout 40 μm to about 90 μm. In particular, the second polymer layer (P2)has a higher layer thickness than the first polymer layer (P1).

The polymer layers (P1) and (P2) of the multi-layer film (F) compriseorganic polymeric materials, which usually have only an insufficientbarrier effect against gases and water vapor. If the oxidizingagent-containing compositions (KM) are packed in a packaging (VP) madeof a multi-layer film (F), which only comprises the two organic polymerlayers (P1) and (P2), water vapor may escape unhindered, so that thewater content in the compositions (KM) changes in an unacceptable wayduring longer storage. To minimize the uncontrolled escape of watervapor from the packaging (VP), the organic polymer layers (P1) and (P2)are therefore used in combination with a barrier layer (BS).

The barrier layer (BS) has a barrier effect against the passage of gasesand water vapor. As contemplated herein, this means that the barrierlayer (BS) reduces and controls the permeation rate of water vapor andgases through the film. A film (F) as contemplated herein, which has abarrier layer (BS) in addition to the layers (P1) and (P2), thus has areduced water vapor permeability and a reduced gas permeability comparedto a comparable film (with the same overall thickness), which only hasthe two layers (P1) and (P2) but no barrier layer (BS).

The barrier layer (BS) is, for example, a thin layer comprising aninorganic material, whereby the inorganic material may be applied toorganic polymer layers by employing vacuum coating techniques (e.g. PVD“Physical Vapor Deposition” or CVD “Chemical Vapor Deposition”).

If the barrier layer (BS) is a layer comprising at least one inorganicmaterial, then the films may be made of metals, semi-metals or metal orsemi-metal oxides, for example aluminium, aluminium oxides, magnesium,magnesium oxides, silicon, silicon oxides, titanium, titanium oxides,tin, tin oxides, zirconium, zirconium oxide and/or carbon.

As contemplated herein, the barrier layer (BS) is made of metallized,oriented polypropylene. Polypropylene is alternatively also known aspoly(1-methylethylene), and is a thermoplastic polymer belonging to thegroup of polyolefins. Polypropylene is produced by polymerization ofpropylene (propene) using various catalysts. Polypropylene may, forexample, be produced by stereo-specific polymerization of propylene inthe gas phase or in suspension according to Giulio Natta. Polypropyleneas contemplated herein may be isotactic and thus highly crystalline, butalso syndiotactic or amporphous. The average relative molar mass may,for example, be controlled by adjusting a certain hydrogen partialpressure during the polymerization of the propene. Polypropylene may,for example, have average relative molar masses of about 150,000 toabout 1,500,000 g/mol. Polypropylene may be processed by extrusion andstretch blow molding, or by pressing, calendering, thermoforming andcold forming.

An oriented polypropylene is defined by the expert as a polypropylenefilm which is stretched during production after an extrusion orcalendering step, namely stretched in the direction of extrusion and/orstretched at about 90° to the direction of extrusion. The film ispreferably stretched in both directions, i.e. films in which the barrierlayer—or the entire film—is biaxially stretched, particularly preferablysimultaneously biaxially. During the stretching step the polymericmaterial is oriented. This is of great importance for the properties ofthe film layer, especially in the case of polypropylenes, since theorientation step determines the shape of the crystalline domains of thepolymeric material and thus the physical properties of the film.

The polypropylene film is metallized. Possible metals are the abovementioned metals aluminum, magnesium, silicon, titanium, tin, andzirconium, especially aluminum. The metals are evaporated onto thecarrier film. According to a preferred embodiment of the presentdisclosure, the ratio of the layer thickness of metal to orientedpolypropylene is from about 1:1000 to about 1:10, preferably from about1:500 to about 1:50, more preferably from about 1:200 to about 1:100.

The production of films with barrier layers comprising inorganicmaterial is known. Also the multi-layer film (F) used as contemplatedherein may be produced by a process which is used for the production ofknown films with barrier layers in the state of the art, as described inthe documents EP 1036813 A1, EP 2371539 A1 and EP 1541340 A1.

The barrier layer (BS) may also comprise a thin layer ofinorganic-organic hybrid polymers. These polymers are known in theliterature under the technical term ORMOCER polymers. A typical ORMOCERpolymer may be produced, for example, by hydrolytic polycondensation ofan organo-functional silane with an aluminum compound and possibly withan inorganic oxide component. Corresponding syntheses are disclosed inthe paper EP 0792846 B1, for example, which is referred to here in full.Inorganic-organic hybrid polymers (ORMOCER polymers) have both inorganicand organic network structures. The inorganic silicate network structuremay be formed in the sol-gel process by controlled hydrolysis andcondensation of alkoxysilanes. The silicate network may be specificallymodified by including metal alkoxides in the sol-gel process. Bypolymerization of organo-functional groups, which are introduced intothe material by the organoalkoxylanes, an additional organic network isbuilt up. The ORMOCER polymers produced in this way may be applied, forexample, to layers (P1) and/or (P2) using conventional applicationtechniques (spraying, brushing, etc.).

The thicker the barrier layer (BS), the greater or stronger the barriereffect for gases and water vapor. The thickness of the barrier layer(BS) may therefore be selected depending on the desired barrier effect.According to a preferred embodiment of the present disclosure, the atleast one barrier layer (BS) has a layer thickness of from about 4 μm toabout 25 μm, preferably of from about 5 μm to about 20 μm, morepreferably of from about 6 μm to about 18 μm.

The material, the design and the layer thicknesses determine thepermeability values of the film. The multi-layer film (F) of thepackaging of the cosmetic product as contemplated herein is exemplifiedby advantageous properties with regard to oxygen permeability and watervapor permeability. The multi-layer film exhibits an Oxygen TransmissionRate (OTR) at about 23° C. and about 50% relative humidity of from about0.1 to about 5 cc/m²/d/bar, preferably of from about 0.2 to about 3.5cc/m²/d/bar, more preferably of from about 0.5 to about 2.5 cc/m²/d/bar,and a water vapor transmission rate at about 38° C. and about 100%relative humidity of from about 0.1 to about 5 g/m²d, preferably of fromabout 0.2 to about 3.5 g/m²d, more preferably of from about 0.5 to about2.5 g/m²d.

As contemplated herein, the permeability values of the film (F) areadvantageously adjusted. The film (F) thus confers advantageous barrierproperties on the packaging, especially with respect to the Water VaporTransmission Rate (WVTR) measured in g/(m²d) or g/(m² 24 h) according tothe ASTM F 1249 method at 38° C. ambient temperature and 100% relativehumidity, and for Oxygen Transmission Rate OTR, measured in cm³/(m²dbar) or cm³/(m² 24 h), where cm³ is equal to cc, at an atmosphericpressure of 1 bar, measured according to the ASTM D 3985 method at 23°C. ambient temperature and 50% relative humidity.

In addition to the layers (P1), (P2) and (BS) described so far, themulti-layer film (F) may also comprise one or more additional layers.These additional layers may, for example, be intermediate layers and/oradhesive layers. As contemplated herein, it is therefore preferred ifthe at least one multi-layer film (F) additionally contains at least onefurther layer selected from the group of intermediate layers (SZ),adhesive layers (SK) and mixtures thereof.

For example, the films (F) may have further intermediate layers (SZ) toincrease the mechanical stability. Intermediate layers may also preventor minimize the permeation of polymers or remaining monomers from apolymer layer into the cosmetic compositions (CM).

To increase bond strength, the films may also include one or moreadhesive layers (SK) to reduce or prevent delamination (i.e. peeling orformation of an air space) between two layers.

A particularly preferred product as contemplated herein the multi-layerfilm (F) comprises, in addition to the first polymer layer (P1), thesecond polymer layer (P2) and the barrier layer (BS), one or morefurther layers selected from intermediate layers (SZ) and/or adhesivelayers (SK).

If the multilayer film (F) contains other layers in addition to thelayers (P1), (P2) and (BS), the following configurations of the layersare possible (viewed from the interior (in contact with the cosmeticcomposition (KM)) to the exterior):

-   a) *Interior*—Layer (P1)—First adhesive layer (SK1)—Layer    (P2)—Second adhesive layer (SK2)—Barrier layer (BS)—*Exterior*,-   b) *Interior*—Layer (P1)—Adhesive layer (SK1)—Layer (P2)—Barrier    layer (BS)—*Exterior*,-   c) *Interior*—Layer (P1)—Layer (P2)—Second adhesive layer    (SK2)—Barrier layer (BS)—*Exterior*,-   d) *Interior*—Barrier layer (BS)—First adhesive layer (SK1)—Layer    (P1)—Second adhesive layer (SK2)—Layer (P2)—*Exterior*,-   e) *Interior*—Barrier layer (BS)—Adhesive layer (SK)—Layer    (P1)—Layer (P2)—*Exterior*,-   f) *Interior*—Barrier layer (BS)—Layer (S1)—Adhesive layer    (SK)—Layer (P2) —*Exterior*,-   g) *Interior* —Layer (P1)—First adhesive layer (SK1)—Barrier layer    (BS)—Second adhesive layer (SK2)—Layer (P2)—*Exterior*,-   h) *Interior*—Layer (P1)—Adhesive layer (SK)—Barrier layer    (BS)—Layer (P2)—*Exterior*,-   i) *Interior*—Layer (P1)—Barriere Layer (BS)—Adhesive layer    (SK)—Layer (P2)—*Exterior*

In any case, the film should be designed so that there is sufficientadhesion between the layers. According to a preferred embodiment of thepresent disclosure, the bond strength of the film is from about 0.1 toabout 10 N/15 mm, preferably from about 1 to about 8 N/15 mm, morepreferably from about 1.5 to about 5 N/15 mm This is measured by theASTM F-904 method. Bond strength is a physical measure of the adhesiveforce between the layers. The bond strength is based on the two layersof a film with the lowest bond strength between two layers of the samefilm. The bond strengths set as contemplated herein lead to a favorablemechanical stability over the storage time of the packaged cosmeticproduct.

Also the strength between two joined (sealed or taped) films should besufficient. According to a preferred embodiment of the presentdisclosure, the seal strength of the packaging (VP) is from about 10 toabout 40 N/15 mm, preferably from about 15 to about 35 N/15 mm, morepreferably from about 20 to about 30 N/15 mm, under the conditions 150°C., 2.54 cm (1″) and 4 kg/cm². The seal strength is measured accordingto ASTM F-88 under the above conditions. The challenge for packagings isto ensure that the mechanical durability of the packaging is alwaysvisible and that the contents are easily accessible to the user.Adjusting the seal strength to these values enables both of theseobjectives to be achieved.

A sealed seam is a seam by which the packaging is closed. Usually, twofilms are placed on top of each other to seal the packaging, which arepressed together by a force perpendicular to the film surface. Byheating the films in the area that is being compressed, parts of thecompressed areas may fuse together, so that the films are weldedtogether. There may also be an adhesive between the compressed foilswhich strengthens the seam.

The product as contemplated herein comprises as a second component acosmetic composition (KM) which is packaged in the packaging (VP) andwhich comprises at least one oxidizing agent, a linear C₈-C₃₀ alcoholand a non-ionic surfactant.

The intended use of the product as contemplated herein is oxidativecolor change. For this purpose—as already described above—usually acosmetic composition (KM) containing an oxidizing agent is mixed with asecond composition (B) which is separately prepared from (KM). In thisway, the ready-to-use oxidative color changing agent is produced.Depending on whether the oxidative color change is intended to achieve ableaching, brightening or coloring effect, the composition (B) maycontain different ingredients. If pure lightening or bleaching is to beachieved, composition (B) contains at least one alkalizing agent. Ifoxidative dyeing is desired, composition (B) often contains oxidationdye precursors in addition to the alkalizing agent. In order to ensurethat the compositions (KM) and (B) may be mixed sufficiently quickly,both the composition (KM) as well as the composition (B) are usuallyflowable, aqueous or water-containing compositions.

As contemplated herein, the composition (KM) is an aqueous composition.The water content of the composition (KM) may bei—based on the totalweight of the composition (KM)—from about 60 to about 97% by weight,preferably from about 75 to about 93% by weight, more preferably fromabout 78 to about 91% by weight, in particular from about 80 to about88.0% by weight. All weight data in % by weight refer to the totalweight of water contained in the composition (KM), which is set inrelation to the total weight of the composition (KM).

The cosmetic composition (KM) contains as first essential ingredient a)at least one oxidizing agent. Preference is given to certain oxidizingagents. It is therefore advantageous in the context of the presentdisclosure if the cosmetic composition (KM) contains at least oneoxidizing compound selected from the group of persulfates, chlorites,hydrogen peroxide and products of the addition of hydrogen peroxide tourea, melamine and sodium borate, in particular hydrogen peroxide. Ascontemplated herein, the use of hydrogen peroxide has proven to beparticularly advantageous.

The concentration of the oxidizing agent in the composition (KM) isdetermined on the one hand by the legal requirements and on the otherhand by the desired effect; preferably from about 0.5 to 20.0% by weightsolutions in water are used. Therefore, as contemplated herein, it ispreferred if the cosmetic composition (KM) contains at least oneoxidizing compound, in particular hydrogen peroxide, in a total amountof from about 0.5 to about 20% by weight, preferably from about 1.0 toabout 18% by weight, more preferably from about 1.2 to about 16% byweight, in particular from about 1.5 to about 15% by weight, based onthe total weight of the cosmetic composition (KM). The higher thecontent of oxidizing agent, in particular hydrogen peroxide, in thecomposition (KM), the greater is the amount of gas produced in the caseof a proportional decomposition of the oxidizing agent. Compositionscontaining a higher concentration of oxidizing agent are therefore muchmore difficult to package in a single packaging (VP) than compositionscontaining a lower concentration. The amount of hydrogen peroxide refersto 100% hydrogen peroxide.

In the course of the work leading to this present disclosure, it wasfound that the product as contemplated herein is particularly suitablefor the packaging and stable storage of higher concentrated hydrogenperoxide compositions (KM). As contemplated herein, packaging (VP)containing compositions (KM) with from about 9 to about 12% by weighthydrogen peroxide showed no volume changes (i.e. no swelling) and nounplanned openings (i.e. the packaging did not burst open) even afterstorage at an elevated temperature for several weeks.

The cosmetic composition (KM) contains, as the second essentialingredient b) at least one C₈-C₃₀ alcohol. In this context, mixtures oflinear C₁₆-C₁₈ alcohols have proved to be particularly useful. Suchmixtures in combination with the further feature c) of the composition(KM) lead to an excellent stabilization of the at least one oxidizingagent, in particular hydrogen peroxide. It is therefore advantageouswithin the scope of the present disclosure if the cosmetic composition(KM) contains at least one C₁₀-C₃₀ alcohol selected from the group oflinear C₁₀-C₂₈ alcohols, linear C₁₂-C₂₆ alcohols, linear C₁₄-C₂₀alcohols, linear C₁₄-C₁₈ alcohols as well as mixtures of theaforementioned alcohols, in particular a mixture of linear C₁₆-C₁₈alcohols. In the context of the present disclosure, the mixture of cetylalcohol and stearyl alcohol known as cetearyl alcohol, in particular amixture of about 50% by weight cetyl alcohol and about 50% by weightstearyl alcohol, based on the total weight of the mixture, has proved tobe particularly advantageous.

The at least one C₈-C₃₀ alcohol is preferably used in certain quantityranges. Preferred embodiments of the present disclosure the cosmeticcomposition (KM) contains the at least one C₈-C₃₀ alcohol, in particulara mixture of linear C₁₆-C₁₈ alcohols, in a total amount of from about0.1 to about 10% by weight, preferably of from about 0.50 to about 6.5%by weight, more preferably of from about 1.0 to about 6.0% by weight, inparticular of from about 1.5 to about 5.0% by weight, based on the totalweight of the cosmetic composition (KM). The use of the above-mentionedtotal amounts of at least one C₈-C₃₀ alcohol, in particular the mixtureof linear C₁₆-C₁₈ alcohols, in combination with the other components ofthe cosmetic composition (KM) leads to a particularly good stabilizationof the oxidizing agent contained in this composition, in particular ofthe hydrogen peroxide.

As the third essential ingredient c), the cosmetic composition (KM)contains at least one non-ionic surfactant. As contemplated herein, theterm “non-ionic surfactant” means amphiphilic (bifunctional) compoundswhich have at least one hydrophobic and at least one hydrophilic part ofthe molecule. The hydrophobic residue is preferably a hydrocarbon chainwith 8 to 28 carbon atoms, which may be saturated or unsaturated, linearor branched. This C₈-C₂₈ alkyl chain is particularly preferred linear.In contrast to anionic, cationic, zwitterionic and amphiphilicsurfactants, however, non-ionic surfactants contain neither cationic noranionic groups. Furthermore, these surfactants also do not contain anycationizable and anionizable groups which may form cationic or anionicgroups depending on the pH value.

The combination of fatty alcohol and non-ionic surfactant ensuresexcellent dispersion of the components of the cosmetic composition (KM)and thus a high storage stability. In addition, the use of such acombination leads to a good spreadability, especially miscibility, ofthe cosmetic composition (KM) with the composition (B) containing theoxidation dye precursors. It is therefore preferred in the context ofthe present disclosure if the cosmetic composition (KM) contains atleast one non-ionic surfactant selected from the group of (i)ethoxylated and/or propoxylated alcohols and carboxylic acids having 8to 30 carbon atoms and 2 to 30 ethylene oxide and/or propylene oxideunits per mole of alcohol, (ii) attachment products of 30 to 50 moles ofethylene oxide to castor oil and hydrogenated castor oil, (iii) alkylpolyglucosides corresponding to the formula R¹O-[G]_(p), in which R¹ isan alkyl and/or alkenyl radical containing 4 to 22 carbon atoms, G is asugar unit containing 5 or 6 carbon atoms and p is a number of 1 to 10,(iv) monoethanolamides of carboxylic acids containing 8 to 30 carbonatoms and (v) mixtures thereof, more particularly adducts of 40 molethylene oxide with hydrogenated castor oil. In the formula R¹O-[G]_(p),the index number p indicates the degree of oligomerisation (DP), i.e.the distribution of mono- and oligoglucosides, and is a number betweenabout 1 and about 10. While p in a given compound must always be aninteger and can assume the values p=1 to 6, the value p for a specificalkyl oligoglucoside is an analytically determined mathematicalquantity, which usually represents a fractional number. As contemplatedherein, alkyl and/or alkenyl oligoglucosides with an average degree ofoligomerization p of from about 1.1 to about 3.0 are preferably used.From the point of view of application technology, those alkyl and/oralkenyl oligoglucosides are preferred whose degree of oligomerization isless than about 1.7 and in particular lies between about 1.2 and about1.7. The alkyl or alkenyl radical R¹may be derived from primary alcoholscontaining 4 to 20, preferably 8 to 16 carbon atoms. As contemplatedherein, alkyl oligoglucosides based on hardened C_(12/14) coconutalcohol with a DP of 1-3, as they are commercially available under theINCI designation “Coco-Glucosides”, for example, are particularlypreferred. The non-ionic surfactants used with particular preference inthe context of the present disclosure are addition products of 40 molethylene oxide to hydrogenated castor oil, in particular the compoundknown under the INCI designation PEG-40 Hydrogenated Castor Oil (CASNo.:61788-85-0).

To ensure sufficient dispersion of all ingredients of the cosmeticproduct (KM), at least one non-ionic surfactant is preferably used incertain total quantities. Preferred embodiments of the presentdisclosure the cosmetic composition (KM) contains the at least onenon-ionic surfactant, in particular the mixture of linear C₁₆-C₁₈alcohols substituted with an average of 20 ethoxy groups, in a totalamount of from about 0.1 to about 5% by weight, preferably of from about0.12 to about 4.5% by weight, more preferably of from about 0.25 toabout 4% by weight, in particular of from about 0.5 to about 3.5% byweight, based on the total weight of the cosmetic composition (KM).

The cosmetic composition (KM) may include at least one liquid cosmeticoil as an additional ingredient. In the context of the presentdisclosure, the term “liquid cosmetic oils” means oils suitable forcosmetic use which are insoluble in water at 20° C., i.e. preferablyless than about 1% by weight of the oil, based on the total amount ofthe water/oil mixture, dissolve in water at about 20° C. However, thecosmetic oil used as contemplated herein is neither a perfume nor anessential oil. The use of cosmetic oils leads to an increasedstabilization of the oxidizing agent, in particular of the hydrogenperoxide, as it is surrounded by the cosmetic oil during dispersion oremulsification with the cosmetic oil and thus protected againstdecomposition due to the reaction with further components of thecosmetic composition (KM). In the context of the present disclosure,certain cosmetic oils are preferably used. It is therefore advantageousas contemplated herein if the cosmetic composition (KM) contains atleast one liquid cosmetic oil selected from the group of (i) esters oflinear or branched saturated or unsaturated C₂-C₃₀ fatty alcohols withlinear or branched saturated or unsaturated C₂-C₃₀ fatty acids, whichmay be hydroxylated, (ii) C₈-C₂₂ fatty alcohol esters of mono- orpolyhydric C₂-C₇ hydroxycarboxylic acids, the triethyl citrates, (iii)mono-, di- and triglycerides of linear or branched, saturated orunsaturated, optionally hydroxylated C₈-C₃₀ fatty acids, (iv)dicarboxylic acid esters of linear or branched C₂-C₁₀ alkanols, (v)symmetrical, asymmetrical or cyclic esters of carbonic acid with fattyalcohols, the esters of dimers of unsaturated C₁₂-C₂₂ fatty acids withmonovalent, linear, branched and cyclic C₂-C₁₈ alkanols or C₂-C₆alkanols (vi) benzoic acid esters of linear or branched C₈-C₂₂ alkanols,such as benzoic acid C₁₂-C₁₅ alkyl esters, benzoic acid isostearylesters and benzoic acid octyldodecyl esters, (vii) synthetichydrocarbons, such as polyisobutene and polydecenes, (viii)hydrocarbons, such as paraffins, and (ix) mixtures thereof, inparticular paraffin oil. In the context of the present disclosure, ithas been found to be particularly advantageous to use paraffin oil, inparticular the compound known under the INCI designation ParaffinumLiquidqum (CAS No.: 8042-47-5), as liquid cosmetic oil. Paraffin oilspreferred as contemplated herein have dynamic viscosities at 20° C. offrom about 20 to about 150 mPa·s (measured according to DIN 51562-1 of1999).

The at least one liquid cosmetic oil, in particular the at least oneparaffin oil, is contained in the cosmetic compositions (KM) preferablyin certain total amounts. This ensures a sufficient stabilization of theoxidizing agent, in particular of the hydrogen peroxide. Preferredembodiments of the present disclosure the cosmetic composition (KM)contains the at least one liquid cosmetic oil, in particular paraffinoil, in a total amount of from about 0.10 to about 25% by weight,preferably of from about 2.0 to about 24% by weight, more preferably offrom about 4.0 to about 22% by weight, in particular of from about 5.0to about 20% by weight, based on the total weight of the cosmeticcompositions (KM).

In the course of the work leading to this present disclosure, it wasfound that the use of the aforementioned essential ingredients b) and c)ensures that the cosmetic composition (KM), which contains at least oneoxidizing agent, may be packaged and stored in the special packaging(VP) without this packaging—which has a barrier layer with a passagebarrier effect for gases and water vapor—expanding or bursting.

In this context, a very specific combination of ingredients a) to c) ofthe cosmetic compositions (KM) has proven to be advantageous. In apreferred embodiment, the product as contemplated herein the cosmeticcomposition (KM) is hydrogen peroxide, a mixture of linear C₁₆-C₁₈alcohols and, as a nonionic surfactant, a mixture of linear C₁₆-C₁₈alcohols substituted with an average of 20 ethoxy groups.

For further optimization of the storage stability, the above-mentionedcompounds are preferably used in certain quantity ranges in thecomposition (KM). Especially preferred embodiments by the fact that thecosmetic composition (KM)

-   a) from about 1.5 to about 15% by weight of hydrogen peroxide,-   b) from about 1 to about 5% by weight of a mixture of linear C₁₆-C₁₈    alcohols; and-   c) from about 0.5 to about 3.5% by weight of a mixture of linear    C₁₆-C₁₈ alcohols substituted with an average of 20 ethoxy groups,    each based on the total weight of the cosmetic product (KM).

The cosmetic composition of the present disclosure may additionallycontain at least one or more cationic surfactants. As contemplatedherein, the term “cationic surfactant” means amphiphilic (bifunctional)compounds including at least one hydrophobic and at least onehydrophilic part of the molecule. The hydrophobic residue is preferablya hydrocarbon chain with 8 to 28 carbon atoms, which may be saturated orunsaturated, linear or branched. This C₈-C₂₈ alkyl chain is particularlypreferred linear. In addition, these surfactants contain at least onecationic group, in particular an ammonium or alkylammonium group.Quaternary alkylammonium compounds, in particular tetraalkylammoniumcompounds with at least one C₁₂-C₂₀ alkyl group, with a physiologicallycompatible anion, in particular a chloride, are preferred.

Typical examples of these ingredients are cetyl trimethyl ammoniumchloride, steartrimonium chloride, behentrimonium chloride,stearamidopropyl trimonium chloride, dioleylethyl dimethyl ammoniummethosulfate and dioleylethyl hydroxyethylmonium methosulfate,especially steartrimonium chloride.

The at least one cationic surfactant, in particular the steartrimoniumchloride, is contained in the cosmetic composition (KM) preferably incertain total amounts. This ensures that the ready-to-use colorant maybe applied to the hair in stable dispersion. Preferred embodiments ofthe present disclosure the cosmetic composition (KM) contains the atleast one cationic surfactant in an amount of from about 0.01 to about2% by weight, preferably in an amount of from about 0.05 to about 1% byweight, more preferably in an amount of from about 0.1 to about 0.5% byweight, in each case based on the total weight of the cosmeticcompositions.

The cosmetic composition (KM) preferably has an acidic pH value in orderto avoid or reduce decomposition of the oxidizing agent used, inparticular hydrogen peroxide. It is therefore preferred in the contextof the present disclosure that the cosmetic composition (KM) has a pHvalue (measured at 20° C.) of from about pH 1.5 to about pH 5.0,preferably of from about pH 2.0 to about pH 4.7, more preferably of fromabout pH 2.3 to about pH 4.4, in particular of from about pH 2.5 toabout pH 4.

The composition (KM) in the packaging (VP) contains the essentialingredients in an aqueous or aqueous-alcoholic carrier, which may be acream, an emulsion, a gel or a surfactant-containing foaming solution.To adjust the desired properties of these dosage forms, the composition(KM) may further contain additional active ingredients, auxiliarymaterials and additives.

The composition (KM) may also contain one or more acids to stabilize theoxidizing agent used, especially hydrogen peroxide. It is thereforepreferred in the context of the present disclosure if the cosmeticcomposition (KM) additionally contains at least one acid selected fromthe group of dipicolinic acid, citric acid, acetic acid, malic acid,lactic acid, tartaric acid, hydrochloric acid, phosphoric acid,pyrophosphoric acid and their salts, benzoic acid and its salts,1-hydroxyethane-1,1-diphosphonic acid, ethylenediaminetetraacetic acidand its salts, sulphuric acid and mixtures, in particular a mixture ofdipicolinic acid, disodium pyrophosphate, benzoic acid and its salts and1-hydroxyethane-1,1-diphosphonic acid.

A particularly high stabilization of the oxidizing agent, especially ofthe hydrogen peroxide, is achieved when the above-mentioned acids areused in certain quantity ranges. It is therefore advantageous in thiscontext if the at least one acid, in particular the mixture ofdipicolinic acid, disodium pyrophosphate, benzoic acid and its salts and1-hydroxyethane-1,1-diphosphonic acid, is contained in a total amount offrom about 0.1 to about 3.0% by weight, preferably from about 0.5 toabout 2.5% by weight, more preferably from about 0.8 to about 2.0% byweight, in particular from about 0.9 to about 1.5% by weight, based onthe total weight of the cosmetic compositions (KM)

The products as contemplated herein obtainable in this way have a highstorage stability as well as a water loss during storage which is withinan acceptable range. No swelling or delamination of the packaging (VP)during storage of these cosmetic products as contemplated herein wasobserved.

The product as contemplated herein is used for the purpose of oxidativecolor change. For this purpose, the composition (KM) packaged in thepackaging (VP), which is the oxidizing agent composition, is mixed withat least one other composition (B) to produce the ready-to-use colorchanging agent. To prevent incompatibilities or premature reaction, thecompositions (KM) and (B) are prepared separately.

A particularly preferred product as contemplated herein comprises acomposition (B) separately prepared from the composition (KM), thecomposition (B) containing at least one compound selected from oxidationdye precursors, direct dyes, alkalizing agents and mixtures thereof.Preferred products of the present disclosure additionally comprise atleast one second cosmetic composition (KM2) which contains at least onecompound selected from oxidation dye precursors, direct dyes, alkalizingagents and mixtures thereof and which is packaged separately from thecosmetic composition (KM).

If an oxidative coloration is desired, the composition (B) contains atleast one oxidation dye precursor. Oxidation dye precursors may bedivided into developers and couplers, whereby the developers are usuallyused in the form of their physiologically compatible salts (e.g. in theform of their hydrochlorides, hydrobromides, hydrogen sulfates orsulfates) due to their greater sensitivity to oxygen.
